Other: Faraday cage, movement stabilization
The Faraday cage is a copper-mesh cage that surrounds the device and test site. It helps eliminate surrounding electrical noise. Movement stabilization will be achieved by placing a velcro strap over the arm to minimize random movements.
- Variability in surface electrical potential measurements [ Time Frame: Within 24 hours of testing ]This study focuses on the ability of the Kelvin Probe to measure skin electrical potential. Because it does so without touching the skin, it is prone to noise - specifically physical movement and surrounding electrical noise. The variability in surface electrical potential is a way to determine how stable the measurements are. It can be determined immediately after testing - and will be used in data analyses (comparing across study volunteers) approximately 24 weeks after testing is complete.
